Re: SS wheels on drum brake cars
I had issues with GM 14x6 disk brake rallys with 205/70 14 tires rubbing the steering arm/tie rod end on my 68 when it had drums; the rubbing was bad enough to cut grooves in the sidewalls. I would assume that the additional inch of a 14x7 SS wheel is on the front side, but I'm not sure. My bet is that the SS wheels will cause rubbing unless you can run a really narrow tire, and or be ready to use a spacer.
I'd put a new post in brakes for those questions, or do some searching there. Wheel and tire doesn't seem to get much traffic.
